The Kalamassery police on Monday seized 12 live bullets that were found hidden in the cavity of a tree on a vacant plot along Muttar river at Manjummal.
The police feel that the bullets were probably abandoned rather than stashed there for future use. They were recovered from a place frequented by people.
A forensic examination is needed to identify the nature of the bullets and their caliber though officials suspect it to be the kind used in pistols.
The police have registered a case and launched a probe to find out how the bullets ended up in the tree cavity and to whom they belonged.
